hi all, transami here. not that anyone has probably given it much thought, but yes, i am alive 🙂 getting back to coding a bit after a few months of much needed sabatical… so i have a question. i’m looking at hosting a wiki on an mac xserve and i started doing some development work on a ruby based wiki. what’s the status of eruby on mac os x? last i heard she’s still barfing due to a dynamic linking issues. thanks, glad to be back, transami ---

To make eruby, libruby is necessary. However, Mac OS X 10.2 (Jaguar) does not include libruby somehow. So you need to build libruby with ruby source in order to make eruby. I don’t use eruby, so I have not tried this. But maybe I think so. If this is too hard, you can use Erb written only with Ruby. Erb is useful.

The problem with eruby lays in how dynamic linking is performed in OS X. When eruby.so is dlopened by Apache Ruby symbols (rb\_\*) are not found despite the fact that they are already present in the process (loaded by mod\_ruby, actually libruby.a is compiled into mod\_ruby during build). I think that to fix it libruby must be made shared and both mod\_ruby and eruby compilation changed to refer it. Than on load a linker will be able to locate symbols for both. I haven’t given it a try yet, maybe sometime next week. > **···** > > ----- Original Message ----- > From: “FUJIMOTO Hisakuni” [hisa@imasy.or.jp](mailto:hisa@imasy.or.jp) > To: “ruby-talk ML” [ruby-talk@ruby-lang.org](mailto:ruby-talk@ruby-lang.org) > Sent: Tuesday, December 10, 2002 3:45 PM > Subject: Re: mac os x eruby > > > At Tue, 10 Dec 2002 20:02:54 +0900, \> Tom Sawyer wrote: > > > libruby with ruby source in order to make eruby.

Really? Please tell me which package in Jaguar include libruby. I could not find “libruby(.a|.dylib)” in packages which are contained in Jaguar and some updates. Therefor, RubyCocoa 0.3 binary package which I distribute include “libruby.a”. Maybe a ruby package of FINK include libruby. I don’t know detail about FINK because I do not install it. thanks, > **···** > > At Wed, 11 Dec 2002 09:33:50 +0900, Gennady F.

I have made a ruby port for darwinports ([www.opendarwin.org](http://www.opendarwin.org)) that solves the link issues.
